forms are strongly suggestive of the Melastomataceous 



type. 



Ouratea (76 species in tropical America and 20 in the 

 Old World) is oue of the finest examples of the Solanum- 

 Cassia type, sometimes with more or less rugose anthers. 



Brackenridgea (5 species, 2 in the Fiji Islands, 1 inPenang, 

 1 in Queensland, 1 in Zanzibar) is an excellent represen- 

 tative of the floral habit of this type, but the anthers open 

 by longitudinal slits or at first by apical pores which are 

 later increased more or less towards the base in lonsritudi- 

 nal slits. Godoya ( 3 species in Peru and New Granada) has 

 10 to 20 stamens but their form is such that they seem to 

 be more properly treated here than in the Dilleniaceous type. 

 Elvasia (4 species in Brazil and Guiana) with stamens 8 or 

 indefinite, up to 20, with oblong or nearly oval anthers 

 basifixed on more or less elongate, filiform filaments, sug- 



gests in some of its species the Melastomataceous type, but 

 in others the filaments are reduced in length and the anthers 

 more elongate, so it may be treated here. 



Blast emanthns (2 species from the upper Amazon, of 

 which 1 also occurs in Guiana) has the 10 declinate sta- 

 mens with very long anthers on short filaments surrounded 

 by numerous staminodia. As far as form is concerned, 

 Wallacea (1 species in the upper Amazon region) is an 

 excellent representative of this type. The fertile stamens 

 are 5 in number and turned to one side at the time of flow- 

 ering. Staminodia are present, and the terminal pores, or 

 single terminal pore, of the anthers are said to be later 

 continued down the sides in lateral slits. In Schnurmansia

be placed without question in this type. Luxemhergia 

 (7 species, all in Brazil) is a peculiar genus in which the 

 indefinite, usually few, anthers are aggregate or connate in 



a column on one side of the ovary. Euthemis (3-4
